由于 JDK /compileOptions 导致 Flutter Android 构建失败

Question

我正在构建一个 Flutter 应用程序并使用 Fastlane。在build.gradle文件中，添加了编译选项，如下所示：

android {
    namespace = "com.jasonholtdigital.mythicgme2e"
    compileSdk = 35
    ndkVersion = "27.1.12297006"

    compileOptions {
        sourceCompatibility = JavaVersion.VERSION_17
        targetCompatibility = JavaVersion.VERSION_17
    }

    kotlinOptions {
        jvmTarget = JavaVersion.VERSION_17
    }
//...
}

这些编译选项绝对会导致构建过程失败并出现异常：

Execution failed for task ':app:compileReleaseJavaWithJavac'.
> Could not resolve all files for configuration ':app:androidJdkImage'.
   > Failed to transform core-for-system-modules.jar to match attributes {artifactType=_internal_android_jdk_image, org.gradle.libraryelements=jar, org.gradle.usage=java-runtime}.

BUILD FAILED in 10s

无论我使用 flutter build aab、fastlane 还是 Android Studio 的典型构建方法进行发布构建，构建都会失败。调试构建工作并成功部署到物理设备。

当我删除这些行时，使用 flutter build aab 构建成功，但 fastlane 失败，并出现以下异常：

FAILURE: Build failed with an exception.

* What went wrong:
Execution failed for task ':app:compileReleaseKotlin'.
> Error while evaluating property 'compilerOptions.jvmTarget' of task ':app:compileReleaseKotlin'.
   > Failed to calculate the value of property 'jvmTarget'.
      > Unknown Kotlin JVM target: 21

谁能解释一下发生了什么事以及我该如何应对这种情况？我为此花费了一天的时间，从我的计算机中完全删除了所有 JDK/Android Studio 内容并重新安装。 JDK 总是会出现一些新问题。

Unknown Kotlin JVM target: 21

看起来很奇怪。在您的配置中，您使用 Java 17。您可以尝试吗

kotlinOptions {
  jvmTarget = "17"
}

或

JavaVersion.VERSION_17.toString()
